Clonal Hematopoiesis: Crossroads of Aging, Cardiovascular Disease, and Cancer: JACC Review Topic of the Week

Area of Science:

• Hematology
• Cardiovascular Medicine
• Genetics

Background:

• Clonal hematopoiesis of indeterminate potential (CHIP) is an emerging cardiovascular risk factor.
• It originates from somatic mutations in hematopoietic stem cells, leading to mutant leukocyte clones.
• CHIP is associated with increased risks of coronary heart disease, ischemic stroke, and heart failure.

Purpose of the Study:

• To explain CHIP and its implications for cardiovascular risk.
• To address clinical challenges in screening, risk assessment, and management of CHIP.
• To provide recommendations for multidisciplinary care and identify knowledge gaps.

Main Methods:

• Literature review and synthesis of current evidence on CHIP.
• Exploration of clinical quandaries and expert opinions.
• Development of recommendations for managing cardiovascular risk in CHIP patients.

Main Results:

• CHIP presents a significant, independent cardiovascular risk.
• Individuals with CHIP have a doubled risk of major cardiovascular events.
• Current management strategies for CHIP-related cardiovascular risk are not well-established.

Conclusions:

• CHIP is a critical, non-traditional risk factor requiring attention from hematologists and cardiologists.
• Further research is needed to establish evidence-based screening and management guidelines.
• Multidisciplinary collaboration is essential for optimal patient care.
